Conditions
Brief summary
This study is a phase 1, open-label, randomized, four-period crossover study to evaluate the effect of food and rabeprazole on the ZN-A-1041 tablet formulation in healthy male and female participants.
Interventions
Participants will receive a single dose of ZN-A-1041 Formulation 1 on each specified treatment.
Participants will receive a single dose of ZN-A-1041 Formulation 2 on each specified treatment.
Participants will receive an oral administration of rabeprazole twice daily (BID) on days 9, 10, 15, and 16 and a single dose on Days 11 and 17.

Eligibility
Inclusion criteria
* Body mass index (BMI) within the range of 18 to 32 kg/m2, inclusive * In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, and vital signs, as determined by the investigator, at Screening and Check-in, as applicable * Clinical laboratory evaluations (including chemistry panel, CBC, and UA with complete microscopic analysis) within the normal reference ranges for the certified test laboratory at Screening and Check-in * Negative test for selected drugs of abuse at Screening and Check-in (includes alcohol) * Negative hepatitis panel (hepatitis B surface antigen, hepatitis B core antibody, hepatitis B surface antibody \[unless consistent with vaccination or immunity due to natural infection\], and hepatitis C virus antibody) and negative HIV antibody screens * For women of childbearing potential: agreement to remain abstinent or use contraception * For men: agreement to remain abstinent or use contraceptive methods, and agreement to refrain from donating sperm * Negative screening test for latent Mycobacterium tuberculosis infection * Able to swallow and retain multiple tablets without chewing or crushing * Able to consume the high-fat meal within the protocol-specified time period and willing to consume 100% of the high-fat meal * Able to fast for 8 hours prior to dosing
Exclusion criteria
* Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal (GI), neurological, or psychiatric disorder, as determined by the investigator * History or concurrent clinically significant hemorrhagic, bleeding abnormalities, as determined by the investigator * Personal or family history of congenital long QT syndrome * History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the investigator * History of GI surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs except that uncomplicated appendectomy and hernia repair will be allowed * History of myocardial infarction * History of febrile illness within 10 days prior to the first dose of study drug, or participants with evidence of active systemic infection, as determined by the investigator * History of acute GI symptoms (e.g., nausea, vomiting, diarrhea, heartburn) as determined by the investigator (or designee) at Screening or Check-in * History of ophthalmological disease or clinically significant abnormality in the ophthalmic examination as determined by the investigator, optometrist, or ophthalmologist * Risk for suicidal behavior at Screening as determined by the investigator's clinical assessment and an answer "Yes" to item 4 or 5 within 2 years of Screening, or to suicidal behavior items on the Baseline/Screening version C-SSRS or suicide attempt within 2 years of screening.
